Apache is sucking up my memory. Is there any simple way to lower the memory usage? At the moment i run a Wordpress blogg with some pictures. One simple webpage with just index.html and squirrelmail. That is what apache as to do.

I'm quite now to this but I think the processes should quit after a while?

I'm on a Debian VPS server 256RAM burst 512.
DirectAdmin.

Please help me if u can.

Look at apache extended-status and you can see how many requests are currently going on. If it is spawning that many children then there is a reason for it.
 
I'm quite new to this, how do I see apache extended-status?

I tryed to add this code to /etc/httpd/conf/httpd.conf and restart httpd but got an error when i restarted httpd.

Code: 
<Location /server-status>
SetHandler server-status

Order Deny,Allow
Deny from all
Allow from .foo.com
</Location>

Why isen't the processes quitting after a while? Or aren't they supposed to do that?

Free Memory 172968 kB
And after restart Apache.
Free Memory 360372 kB

As I wrote, I only got one wordpress blogg, one simple page with just index.html and Squirrelmail.

Something has to be wrong here?

Apache's configuration file has a setting for how many processes to start and keep alive.

There's no way to tell from just a post. Wordpress can definitely use a lot of resources.

You need to edit the file below
nano -w /etc/httpd/conf/extra/httpd-info.conf
Click to expand...
Then just make something like this

<Location /server-status>
SetHandler server-status
Order deny,allow
Allow from all
</Location>

ExtendedStatus On
Click to expand...
Now save the file and restart HTTPd.
Go to http://your-domain/server-status or http://serverIP/server-status
 
Enabled server-status

Okey, I have enabled server-status now. What should I look after? Shall I copy/paste anything for you?
 
When this information was saved I logged in to my wordpress blog. Apache was at this time using 172Mb RAM. Is there anything I can change to lower the memory usage?
